Yes, you can bike across the Howard Frankland Bridge. It has a multi-use path that's separated from the highway by a barrier the entire span of the bridge, and I rode it across Tampa Bay in both directions.
Westbound starts at Cypress Point Park in Tampa, which is where I park. It follows the trail onto the bridge and comes off on the St. Petersburg side, finishing at 116th Ave. That one is 9.8 miles.
The eastbound ride starts at 119th Ave, crosses the bay on the path, then follows surface streets back to Cypress Point Park. That one is 8.8 miles.
The bridge part itself takes me about 14 to 15 minutes each way. There are some shade structures on the bridge but no water, so bring your own. Tampa is flat, so the bridge is where the climbing is. Both videos are real time with no speed-up, so you see the whole crossing.
